lApplicaticn filed: Apri-L 4,:V

This invention., relates.l to new and useful improvements in,V article forming devices which are particularlyadapted torusein the manufacture of lamp shades.

Oneof the obj ectsot my invention is the provision cfa device of, thekindydescribcdf. which isespecially adapted, for use-in for1n ing aseam 1n a lampshade afterthe application ofv adhesive to a portion otheblank from which the ,shade isi'orined.

A furtherJ object ofmy invention is` the. provision of adevice of the kind described which includes, av form I upon which lamp shades or `other articles ofpaper or similarVL V material are'placed .when it is desired to glue parts thereof together, means beingincluded in the. construction of the-device whereby to guide the parts to be glued and ,toretain themA in proper position duringtheoperation, Thedevice further include smeansifor subjecting;`

the parts to heat and pressure to facilitate the; drying ofthe adhesive. 1 l

Many other i obi ects yand1advantages of the construction herein shown .and described will beobvious to4 those skilled in' the:` art from the.

The barhforms the 'sup-porting hanl and is attached `a,t ;its,innerend tothe base plate 3 by means of the, screw bolts'f' The outer` endy of theibari projects a suitable d-istancebeyond the outer edgeof the base plate 3, and attached thereto isa substuitially,cone:`

shaped form 8, the outer end of which is flush witlr the outer-rend ofthe bar Band secured to the bar `by; means Vof the screwk bolts rI he` uppermost bar 6is rpreferably'n'aounted fforlmovement toward and away from the v bar 5 and lies parallel therewith, its ends'being flush with theielltlsfof therbar 5. The bar 6 is revided f xdjacent.fit-sA linnenend, with lateral -y-proj ecting studs 10 whiclrarge slidably mounted w-ithin-"slotsll formed Ain; the gui-dei plates 12 secured tothe bar adjacent its inner end. In order tofu'rtfher guide the moyenient of ,thejbar Gand retain the 4same parallel with Vthe-bar 5, guiding -platesl are arrangechat a point adjacent the inner yend of the form 8 with; their. upperlends, projecting Lloeyondthe upper face of the ba'r "6 as shown in Fig. 2v.-

the lpla-tegel?)V andactuatedby means of an arm 15,;o`neend :of which is Vattached tothe 1.05

with a treadle bar 20. From this it will `be `apparent that upon downward movement of of the spring normally urging the bars apart as shown in Fig. It will be apparent that when the oval-shaped cam 14 is in a lock-- ing position and the treadle 20 released, the tension ofthe spring 21 is preferably such that it will not force the two bars apart, and in order to impart a slight movement to the cam 14 to assist'in the moving of the bars away from each other, a lever 22 is attached to the pivot 16 for imparting slight movement to the pivot when it is desired to release the ca I The opposed faces of the bars 5 and 6 are each provided with rows of spring pressed pins 23 and 23', the pins in the row of one bar being arranged alternate withthe row of pins on the other bar, as illustratedV in Fig. 2, so as to evenly distribute the pressure of these pins against the edges of an' article placed between the two bars. Thus, when the l two edges B and C of the blank 8 are positioned between the bars, the spring pressed pins 23 will have a tendency to properly position the edges whereby to cause the adhesive on edge B to adhere to edge C. In order that the end portions of the edges B and C will-be uniform, guide pins 24 and 25 are ar- `ranged at the outer ends of the bars 5 and 6 so that the end portions of the blank may be positioned against these pins as illustrated inFigpG.

the pins 23.l

i the adhesive applied to the edge B will be glued togetherand will be retained in this `In placing the edges of the blank A in position between thel bars 5 and 6, it will be noted that one of the yedges is arranged in abutting relation with "the row of pins 23 which are arranged upon one side of thelongitud'inal center ofthe bar ,while the other edge of the blank is arranged in abutting relation with the pins 23 which are arranged upon the side of the longitudinal center of the bar 6 directly opposite the position of Ihe above is clearly illustrated `in Fig. 6, and it will be noted that when the edges are properly positioned against the pins "23 and 23', they will be clearlyv overlapped so that engaged by the edge C. From this it will beV apparent that when the bar 6 is moved downward toward the bar 5, the 'overlapped edges will be properly positioned before being 'position until the adhesive has thoroughly dried.

In order to facilitate drying of the adhesive the edges together,

applied to the edge B and which adheres to the edge C, a burner 26 is arranged within the form 8 and disposed directly beneath the bar 5 so that the heat `from the burner will be applied directly to the parts being glued to- 0'ether'.

o It will be apparent from the foregoing that in using myimproved device the form A has the adhesive applied at B, the edges then placed between the bars 5 as shown in Fig. 6, with the end portions abutting the pins 24 and 25, and the overlapped edges abuttingv the pins 23and 23f so that when the shade is completed, the ends thereof will be even as shown'v in Fig. 8; After the edges have been made uniform, the foot treadle 2() is pressed downwardly, causing the'cam 14 to turn and force the bar 6 toward the bar 5, clamping-the edges together. rllhe shade is allowed to remain inthis position a short duration of time and upon release of the same, if the cam 14 fails to moveupon release of the treadle 20, the lever 23 is actuated to cause the cam to be returned to an inoperative position as i shown in Fig. 2 by means of the coil spring 2l.`

Having thus described my invention, 1t is `obvious that various immaterial modifications may lie-made in the same without departing from the spirit of my invention hence 1 do not wish to be understood as limiting myself to the exact form, construction,
